Inthe annered drawings, A represents the plough-beam, and the plough-handle to which said beam is secured; 0 represents the plough-blade; allot whichare made of the ordinary materials and in the usual forms- In'stead of attaching the plough-beam directly to the plough-handle,-I constructa metallic clamp, D, which isa plate of metal with two jaws formed nearxthe centre'thereof, (see xxx) and a slot in the shank above, and one in the shank below the said jaw, as shown at z 2, Figure 2. This clamp is placed so that the end of the plough-f h fi h lyqgghinlhe iawQ- whilethe shanks above and 'belq am "attached to the plough-handle. plough-beam is secured tothe clam'p D by means of a bolt at the end, (not shown,) and the set-screw m. a represents a screw which passes through the plough-handle and the slot in the upper shank of the clamp; a and b are two nutsiwhich-are upon the screw d.
